@Cycloptichorn,
I admit the article was older than I thought, and I have heard rumblings about this in the past, but seriously cyclops, Obama's administration is the first one that would actually seriously consider this sort of thing even sensible, let alone try to implement. Be honest, Obama is proposing to punish greenhouse gas emissions. I haven't heard him mention cows yet, but he most certainly is energy companies, and both are just as bad in terms of policy. Throw in the fact that global warming is not in any way shape or form a settled science, no way, so the policy is based upon pop science, not sound science.
A thought about taxing cows, who is going to pay the tax on all the wildlife, deer, elk, bison, on down the chain, the trillions of prairie dogs, the list is endless, as surely they also emit methane in some quantity. Who pays that tax, government? And who do they pay? And how about human methane. Do taxpayers now pay a fat tax, or a methane tax, based upon how much methane producing diet they intake? And what bureaucracy will knock on your door to monitor this? I know that you believe the green economy is a job producing economy, perhaps this is the type of jobs you refer to?
Liberals have painted themselves into a corner of total silliness.
